Is your feature request related to a problem? Please describe. I would like to have the option for exporting the overlay to PNG files so that I can then use them in another application (Adobe Premiere). For example Garmin VIRB has the same functionality.

Describe the solution you'd like I would like to be able to use an optional parameter to export only the overlay (indicators), e.g. in 1 second intervals.

Describe alternatives you've considered Export only the overlay layer to a video file.

Hi,

Feature added in the last commit. Now you can render image per image:

$ mkdir png
$ ./gpx2video -v -m GH020340.MP4 -g ACTIVITY.gpx -l layout.xml -o png/image-XXXXXX.png image

By default, background is transparent.

Just use "image" widget to apply background color:

      <widget x="0" y="0" width="1920" height="1080" position="none" display="true">
          <type>image</type>
          <background-color>#00aa00ff</background-color>
      </widget>
